PURPOSE

Reference values of Frequency Volume Chart (FVC) parameters are available for children until the age of 11, but are

lacking for adolescent and adult enuresis patients. We aimed to describe reference values for this group.

MATERIAL AND METHODS

Retrospective, descriptive cohort study, in 907 patients between 2003 and 2013, aged 11 years and older, suffering

from enuresis of at least one wet night per fortnight.

The main FVC and uroflowmetry parameters of interest were: maximum voided volume, 24h urine production and

nocturnal urine volume including first morning void. Nocturnal polyuria (NP) was defined based on both International

Childrens’ Continence Society (ICCS) and International Continence Society (ICS) definitions. Data of all patients were

collected from the medical files.

RESULTS

Small bladder capacity for age was present in 41% of men and 30% of women. Prevalence of NP differs tremendously

when assessed by the ICS or the ICCS definition: following ICS guidelines, NP was present in 96% of our male and 93%

of our female population. Following ICCS guidelines, NP was present in 27% of men and 41% of women.

CONCLUSIONS

Both small bladder capacity and nocturnal polyuria were found frequently in our adolescent and adult enuresis patients,

which is in line with the current thought on causal factors.

NP prevalence is very different when assessed by using ICCS or ICS definitions, respectively. To make outcome research

results comparable, coordinating activities to conform these definitions could be worthwhile.
